Application and March 1c, 1908; Serial No. 421,646.

To all whom 'it may concern. 1

Be it known that I, LEONARD W. AsHLnY, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Hinges; and I do hereby declare that the following is a full, clear, and exact description. thereof.

My invention has for its object to provide simple, economical and eflicient self-closing hinges, and it consists in what is'herein particularly set forth with reference to the accompanying drawings and pointed out in claims. 1

Figure 1 of the drawing represents a partly sectional elevation proved hinges full open, section being indicated by 4; Fig. 2, an elevation of a fragment of the closed hinge; Fig. 3, a fragment of the open hinge partly in section as indicated by lines 33 in Fig. 1, and Fig. 4, a sectional view on planes indicated by lines 4,-4 in Fig. 2.

Referring by letter to the drawings, A indicates the stationary or jamb-leaf, B the swinging-leaf and C the pintle of the hinge. A lower knuckle b of the stationary leaf is inclined at the tpp, and the high portion of this knuckle is provided with a socket with which an anti-friction ball 0 is engaged.

A knuckle d of the swinging-leaf has an inclined lower end that rides on the ball 0 with which it is kept in contact, by means of a spiral-spring e surrounding the pintle C within an upper knuckle f of the stationary leafA, this spring being at all times under compression between the head 9 of said pintle and the upper horizontal end of of one of my imthe plane of the line 1-1 in Fig.

40 the knuckle d aforesaid that projects into said automatically close knuckle f, it being preferable to interpose a washer i2, and balls 2' between said spring and partially incased knuckle. The lower end of the pintle is screw-threaded and engages a nut-knob j by which it is held in engagement with the aforesaid knuckle. The pintle is held against turning, by a lug is of its head in engagement with a recess in the upper knuckle f of the stationary leaf.

Owing to gravity, a door hung in connection with the swinging-leaf of the hinge will at anytime it is released after opening, but to hold said door open at a predetermined distance, the inclined end ball seated in of the knuckle of said leaf is provided with a concave notch m for engagement with the ball on which said knuckle rides.

I claim:

I 1. The combination with a hinge comprising in its construction a stationary leaf havingthe upper end of its lower knuckle inclined and provided with a socket in. the highest portion of the inclination, a swinglng leaf having the lower end of its knuckle inclined and the upper end of this knuckle projected into the upper knuckle of the stationary leaf," and a pintle 'connecting said leaves; of a ball seated in the socket of the inclined end of the lower knuckle of the stationary leaf and having bearing-contact with the inclined end of the knuckle of the swinging leaf, and a spring under compression 1n the upper knuckle of said stationary leaf between a head of the pintle and the knuckle of said swingin leaf.

2. The combination with a hinge comprising in its construction a stationary leaf having the upper end of its lower knuckle inclined and provided with a socket in the highest portion of the inclination, a swinging leaf having the lower end of its knuckle inclined and provided with a concave notch at the lowest portion of the inclination, the uppenend of this knuckle being projected into the upper knuckle of the stationary leaf, and a pintle connecting said leaves; a the socket of the inclined end of the lower knuckle of the stationary leaf and having bearing-contact with the inclined end of the knuckle of the swinging leaf, and a spring-under compression in the upper knuckle of said stationary leaf between a head of the pintle and the knuckle of said swinging leaf.

3. The combination with a hinge comprising in its construction a stationary leaf having the upper end of its lower knuckle inclined and provided with a socket in the highest portion of the inclination, a swinging leaf having the lower end of its knuckle inclined and the upper end of this knuckle 'p rojected'into the upper knuckle of the stationary leaf, and a pintle connecting said leaves; of a ball seated inthe socket of the inclined end of the lower knuckle'of the stationary leaf and having bearing-contact; with the inclined end of the knuckle of the swinging leaf, anti-friction balls supported on the u per end of the knuckle of the have hereunto my hand at Milwaukee, in swinging eaf, a pintle-engaged washer surthe eounty of M1lwaukee and State of Wismounting the antifriction balls, and a consln 1n the presence of two Witnesses.

. spring under compression in the upper L. W. ASHLEY. 5 knuckle of said. stationa leaf between a Witnesses:

head of the pintle and sai washer. N. E. OLIPHANT,
